Italy recorded the shock victory of the tournament with a
win at the same venue over France, but they then suffered a
defeat by Scotland in Murrayfield.
This was Wales' sixth consecutive win over the Azzurri and a fourth successive away victory for Wales in the Championship - a feat they last achieved in 1979.
"It was about territory, putting the ball in the right areas and making sure the points count," added Jones.
"You have to build a win in places like this - it's a three-six-nine point game.
"The early points in the second half settled us down and we defended superbly and we managed to pull away in the end."
Wales now travel to face Scotland at Murrayfield in two weeks, knowing a win would see them host England in the final round of the tournament at the Millennium Stadium with a possible Six Nations title to play for.
Jones, who extended his record to 31-times as captain against the Azzurri, paid tribute to Wales' dominant scrum, the one area of the game that Italy traditionally seek to dominate.
Wales' front row of tight-head prop Adam Jones, hooker Richard Hibbard and loose-head prop Gethin Jenkins completely outmuscled their Italian opposite numbers at the scrum.
"Robin McBride [Wales forwards coach] is happy and there are six front rowers with big cheesy similes in [the dressing room] and they will be looking forward to the plaudits," said Jones.
"It's the second game in a row and it hasn't been pretty, but we have managed the win, with wonderful endeavour."
